Through a study of Ra Province (northeast Viti Levu Island, Fiji) involving both archival research and community engagement, we highlighted a long history of Indigenous population mobility. Many coastal settlements have mostly undocumented histories of relocating inland due to shoreline retreat and land loss over recent decades. Studies of Navutulevu and Vunitogoloa use oral histories and nineteenth-century accounts to show this. More recent autonomous relocations, identified through field surveys in Madhuvani and Navuniivi, are regarded as ‘invisible’ because such major adaptation responses are not usually included in most formal or published reviews of community relocation in the Pacific.

Based on our results and a broader understanding of societal evolution in the Pacific Islands region, we concluded that population mobility and settlement relocation have historically been common on (comparatively small and remote) oceanic islands, often in response to changing environmental conditions. Therefore, the possibility of future relocation might seem less intimidating for many coastal residents because of this history. The idea that future relocation is rare and therefore requires extensive funding and policy support, rooted in post-globalization norms, is inaccurate. In reality, it could undermine the resilience of Pacific Island communities by dismissing their histories of autonomous adaptation.
